I recently bought an USB SuperDrive for my 2012 MacBookPro. When I tried to use it, it didn’t accept any DVD’s in the drive, but was working on another machine I have (MacBook Air). That led me to search the net for other people with maybe the same problem.
Found the following description:
1. open a terminal
2. type (on a single line)
sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
3. Insert mbasd=1 in the <string></string> value below the <key>Kernel Flags</key>
The file will then look like:
<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”>
<plist version=”1.0″>
<dict>
<key>Kernel Flags</key>
<string>mbasd=1</string>
</dict>
</plist>
4. Save (press Ctrl-X, answer yes to save by pressing Y, press enter to confirm the file name). 5. Restart your machine. That’s it!
It worked like a charm!!
